True or false?
The posterior thigh compartment is in charge of flexion of the hip and extension of the knee
False
The posterior thigh is in charge of extension of the hip and flexion of the knee
The anterior thigh is flexion of the hip and extension of the knee
Which muscle compartment flexes the toes and flexes the ankle

What is significant about muscle compartments?
- muscles within these groups often cross the same joints in the same way
- so will have the same actions
- they tend to all receive the same blood and nerve supply

abduction of hip
What muscle compartment does the superior gluteal nerve innervate?
the superior gluteal compartment
Which muscle compartment is this?
